ok i changed the .22 cap had no effect so now i am really trying to understand what is happening or not happening here with this set. i took vlotages again with the bias at min and the g1 164v 163v 164v g2 1145v 1142v 831v cathodes 338v 310v 338v and these i guess would vary depending on where the pots are. the green drive with bias at min comes right up the way all 3 colors should but there is no blue or red that comes up unless the bias is at almost max and this is with 2 different crts.. these voltages look to be somewhat where they should be with the bias at min so the question is what is preventing the screen from being brighter then it is and or what is preventing the red and blue from coming up the way the green does with the bias down . the crt bias, this works with the blanker circuit so maybe there is other issues within that circuit and would it affect the drives ability to show lines needed for setup and ultimately help in the brightness area via the drives. however i do lack some understanding in some areas of this type of electronics but i do try.
